A. DEAN, OF RICHMOND, INDIANA.

WASHING-MACHINE.

Specification of Letters Patent No. 27,538, dated March 20, 1860.

To all whom 'it may concern:

Be it known that I, ALEXANDER DEAN, of Richmond, in the county of wWayne and State of Indiana, have invented certain new and useful Improvements in lashing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and to the letters of reference marked thereon.

The nature of my invention consists in the use of two circular brushes, C, D, in combination with a tub B; the brush D being secured to the bottom of the tub, and brush C, forming the rubbing disk or follower. And also in a peculiar arrangement of levers, E, H, and links F, G, with the tub and follower, for the purpose of vibrating the tub and follower in opposite directions simultaneously.

Figure l, shows a front view of the machine with the tub bisected to show the position of the brushes. Fig. 2, shows a side view of the machine. Fig. 3, shows the rows of bristles on the disk. Fig. t, shows lever, I-I, and its relation to Disk, C. Fig. 5, shows lever, E.

A, A, A, A, constitute the framework of the machine, which may be constructed after any model or plan for similar machines. This method of constructing machines is so much in vogue that a detailed description is deemed unnecessary. It being necessary that the frame should be sufficiently wide to allow the tub to vibrate freely; and suficiently strong to endurevthe strain of the machinery. Its construction is sufficiently shown in the drawing.

B, is the tub of any required size, with nearly perpendicular sides. It is pivoted upon an upright shaft, Z).

b, is an upright shaft secured firmly to the bottom of the tub. It passes through upper'bar, A, and has a step in lower bar, A. Its length should be about eighteen inches so as to give sufficient accuracy to the motion of the tub, the whole being so arranged that the tub may vibrate freely.

C, is the follower or rubbing disk. Its shape and arrangement of parts are shown at Figs. l and 3. It is in fact nothing but a large circular brush upon an upright shaft with a lever, H, by which it is vibrated. The bristles upon this disk are disposed in radial lines; eight of which approximate the center, and eight other of only half this length. In use however there are two or more rows of bristles placed in contact in each line. I do not wish to be understood as confining myself to the exact arrangement of bristles shown. It is the arrangement most in favor with me, and I believe it to be the best.

D, is a brush or disk similar to disk, C, both in shape and the arrangement of its bristles; but it is firmly secured to the bottom of the tub. It will be seen that these brushes are thus made to antagonize with each other.

Brush C, is a little smaller than the inside circumference of the tub so as to allow it to play freely without contact of its sides.

E, is a lever whose shape is shown at Fig. 5. It plays freely upon its fulcrum, E', and has staples, j, g, equidista-nt or nearly so from its center of motion for the links, F, Gr.

F, is a link with an eye at one end secured in staple, f, and a hook at the other end falling in staple, y. Thereby connecting levers, E, and, H.

G, is a link similar to link, F. One end is secured to the lower end of lever E, by means of staple, g, the other end falls in an eye, e, upon the bottom of the tub.

Now it is obvious that if lever E be moved to the left, brush C, being connected with it by lever, H, and link, C, must also move to the left. But the lower end of lever E moves to the right, and being connected with the tub by link, G, the tub must also move to the right. If lever, E, be moved to the right, the brush, C, will also move to the right, and the tub to the left. Thus it will be seen that I obtain the vibration of brush, C, and the tub simultaneously in opposite directions.

H, is a lever, Figs. 1, 2, 4, permanently xed upon shaft, I, and thereby connected with brush or disk C.

I, is a shaft connecting lever, H, and brush C. It has bearings in bars, A, A', which in conjunction with rounds, a, a, form a. movable frame for the support of disk, C, and its appendages.

Instead of disk, D, slats armed with bristles may be nailed upon the bottom of the t-ub or it may be divided into four or eight sect-ions.

This machine is not expensive in construction, is substantial and not liable to get out of order and washes well.

Operation: The operation of this machine is so similar to others now in use that de-y scription is unnecessary.

I am aware that washing machines are now in use in which the disk and tub vibrate in opposite directions simultaneously; this therefore I do not claim as a new result. Neither do I claim as new any of the devices by which I produce this result, when indeendently and of themselves considered.

I do claim as new and useful and desire to secure by Letters Patent7 1. The combination of the vibratingl disk 0r brush C, with the vibrating tub and brush, D, or the equivalent to, D, herein de- 15 scribed; the whole being arranged in a manner substantially as described.

2. I claim the 'combination of the lever E, and links F, G, with the brush, C, tub B, and disk, D, substantially as shown.

ALEX. DEAN.
